I think the challenge is the side switch timer restricts the free movement between chess pieces.
I know it's been shortened recently, but even 6 hours is enough to cause frequent side switching to be problematic for folks that like to fly with a squad. Let's say I log in, and the only squad member on. I see the bish are the low numbers, so I switch. Now I am here for 6 hours. As others in the squad come on, they too have to switch lest we be labeled spiez (zoomoog!). So now, 10 squaddies are on, we have all switched sides, and now the bish are the high numbers, and we have ENY. Since we are stuck in bishland and it's not kosher to divide the squad into opposite sides anyway, we haven't accomplished our original goal of side balancing, we are more or less screwed.
The AK's have resolved this by rotating each tour, and that's the best I think we can do.
